Which tax provision do home owners often overlook?

AS: You can deduct mortgage insurance premiums [or PMI] if you were required to get PMI as a condition of receiving financing on your home. Some people will overlook that, although it’s typically disclosed on the 1099 that you receive from the bank, along with all the deductible information you need.

note: The PMI deduction has been extended through 2013 and is retroactive for 2012.

[Another area of tax-filing confusion is] whether you’ve correctly treated any points you paid if you refinanced. In a new home purchase, the points can be deducted [in the tax year you paid them]. But typically in a refinancing, you have to amortize and deduct any points you paid over the life of the mortgage, and people tend to forget that after a couple of years.
